WILLIAM G. SHABPLESS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND DAVID H. \VATTS, OF SAME PLACE.

TILE-LINED STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 337,629, dated March 9, 1886.

Application filed August 15, 1885.

To all whom it may concern:

Be it known that I, WILLIAM G. SHARPLESS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Tile-Lined Structures, of which the following is a specification.

The object of my invention is to construct a strong and durable tile-lined tub, tank, vat, or like structure, and this object I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of the outer r5 shell creasing of the structure; Fig. 2, a sectional perspective view, on a larger scale than Fig. 1, of part of the structure with the tilelining applied thereto; Fig. 3, a transverse section of the structure on a still larger scale, and Fig. at a longitudinal section.

The shell or casing of the structure is composed of the side plates, A A, end plates, B B, and bottom plate, D, the side and end plates being provided at the ends with flanges cl,

2 5 whereby they may be readily secured together by bolts or rivets, and both side and end plates having at ornear the bottom internal flanges, a, bolted, riveted, or otherwise secured to the bottom plate, D, so that a perfectlyrigid and water-tight structure is produced. To the inside of the shell or casing thus constructed I apply a layer, f, of cement, to which are secured the tiles F, forming the lining of the structure. The upper edges of the top row of 3 5 tiles are covered and protected by an internal flange, g, on the side and end plates of the casing.

The plates composing the shell are preferably of cast-iron, for the reason that the cement Serial No. 174,471. (No model.)

used for securing the tiles takes a much firmer 0 hold upon this metal than upon any other, and a cast-iron plateis cheaper than a wroughtiron plate, which would have to be provided with barbs or recesses to retain the cement.

The making of the shell of a number of sep- 5 arate plates is much preferable to the casting of said shell in one piece, as, owing to the large size of the shell and the thinness of the metal composing the same the tendency of the shell to warp and twist when made in one piece renders this method of manufacture extremely difflcult and expensive.

Tiles may be applied to the outside of the shell or casing as well as to the inside, if desired, the side and end plates of the shell hav- 5 ing at the top external flanges for protecting the top row of the outside tiling.

I claim as my invention 1. The within-described structure, consisting of an outer metallic shell composed of side, end, and bottom plates secured together at the corners and havinga lining of tiles cemented thereto all substantially as specified.

2. The withindescribed structure, consisting of an outer shell composed of side, end, 6 and bottom plates of cast-iron having flanges cast therewith, by which the plates are secured together at the corners, and having a lining of tiles cemented directly to the inner faces of the plates, all substantially as speci- 7o fied.

In testimony whereofI have signed my name to this specification in the presence oftwo subscribing witnesses.
